The gear progression in this game isn't that big. It's not like if you had a full set of blue or even purple gear (if they even exist at this level) Autoch wouldn't be killing a person each time he charged. I just did it because it's something different. Since there are many classes that can rez it's really that big of a deal to wipe. I think my group wiped 5 times on the trash and 0 times on bosses minus Autoch which I was pretty sure we weren't beating since he's way overtuned. You got trash that is genuinely difficult since you got mobs that can kill you in 3 seconds when all their big moves are up. Like I said, it felt like it was borderlining impossible but eventually you won't get as bad a break when a mob tries to do a 3 hit combo of doom since it'll miss a hit or at least you'll block two and then you'll beat it. Of course if you've some kind of well-oiled machine of death you can heal through that too or dps through that but it's not needed. That said it's kind of humbling when you see a mob hits you for like 1500/1000/1000 in succession, and makes me wish I was a Paladin.
Even Autoch who is apparently the hardest boss in the game right now isn't really that bad. My group of 1 healer + 3 others got him to 20%, and when you consider that each time he charges, someone basically dies, that's not that bad of a result. The fight is way too gimmicky as it's utterly impossible to heal through his charge damage without 2 healers so you have to stand in a spot where he can't charge at all, and I don't like to bother with gimmick position fights unless there's no choice. After 3 wipes we figured that there was no way this guy is going to die unless we stand in some magic spot but then people were too tired to continue. I expect they'll fix that encounter up by lowering the charge damage so that it no longer instantly kills someone the moment he KBs the tank. I mean, 855 damage per tick dot is more DPS than his melee damage on the MT and he does that on one person every 10 seconds.
Believe it or not, I actually find well-oiled machine of death to be rather boring. I ran one when I was in EQ and it's cool to tell about your friends how your 3 guys can do what others need 30 to do it but it's actually a lot more boring than it sounds like. Then again maybe it's not entirely fair to call my group pickup since I did all the positioning/moving so that nobody ended up standing in a frontal cleave or a fire and that's the stuff that usually trips up pickup groups.
